Welcome to the MMS Blog! The blog is one of our items for this release, and we hope you will find it useful. Here we will post our release highlights, give advice, answer user questions, plus tell you a bit about what we’re working on. We are pushing new releases to production every two weeks.
For this release, we implemented a brand new onboarding flow for monitoring and backup which will streamline your MMS setup. On the UI side, we updated our theme and made the skin of MMS look much nicer.
The big ticket item in this release is the ability to restore sharded clusters to discrete checkpoints in time using MMS Backup. You can now schedule checkpoints taken at 15, 30, or 60 minute intervals. During a checkpoint, if the balancer is stopped, a token is inserted in all shards and config servers to mark that point in time. The checkpoints are stored in the oplog, giving you the ability to restore to any successful checkpoint within the last 24 hours.
We are also pleased to announce a new MSI installer for the Backup agent on Windows - it now runs as a service. Additionally, the backup agent init script for RPM was tweaked to automatically restart after a server reboot. Formerly, administrators had to restart it themselves.
To summarize, the February 19th release contains:
- More granular restore points for sharded clusters
- MSI installer for the backup agent on Windows
- Preparation to support MongoDB 2.6
- Better, more intuitive sign up and installation of agents for Monitoring and Backup
- The “Lock %” alerts are now calculated using the same definition of “Lock %” we show in charts
- If a particular host changes state, we will now automatically close alerts (for example, MMS will auto-close replication lag alerts if host becomes primary)
